function idx = findClosestCentroids(X, centroids)
%FINDCLOSESTCENTROIDS computes the centroid memberships for every example
%   idx = FINDCLOSESTCENTROIDS (X, centroids) returns the closest centroids
%   in idx for a dataset X where each row is a single example. idx = m x 1 
%   vector of centroid assignments (i.e. each entry in range [1..K])
%

% Set K
K = size(centroids, 1);
m = size(X,1);
% You need to return the following variables correctly.
idx = zeros(size(X,1), 1);

% ====================== YOUR CODE HERE ======================
% Instructions: Go over every example, find its closest centroid, and store
%               the index inside idx at the appropriate location.
%               Concretely, idx(i) should contain the index of the centroid
%               closest to example i. Hence, it should be a value in the 
%               range 1..K
%
% Note: You can use a for-loop over the examples to compute this.
%
% min = 10000;
% for i=1:m
%     for j=1:K
%         dis=norm(X(i,:)-centroids(j,:));
%         if(dis<min)
%             idx(i,:)=j;min=dis;
%         end
%     end
% end
for i = 1 : m,
	T = [];
	for j = 1 : K,
		T = [T ; X(i,:)];
	end
	[Max , idx(i)] = min(sum((T - centroids).^2 , 2));
